Patent KR-20180128855-A (KR)
Inventor: SHIN IK SOO
IPC: H01B1/12
Filed: 2018-05-23
Abstract: The present invention relates to an electrolyte for electrochemical devices and a preparation method thereof. More specifically, the electrolyte for electrochemical devices comprises: a first electrode; a second electrode spaced apart from the first electrode; and a carbon quantum dot ionic compound applied to an electrochemical device filled with an electrolyte between the first electrode and the second electrode, having an average diameter in a range of 2 to 12 nanometers (nm) and a surface charge less than or equal to −20 mV, and having salt forms of a carbon quantum anion and a metal cation. The electrolyte for electrochemical devices according to the present invention has very small dissociation energy of anions and cations, thereby improving ion conductivity, and since a moving speed of anions is relatively very slower than that of metal cations, an electrochemical device can be constructed only by movement of metal cations. Also, since ionic polarization is large, and thermal chemical/electrochemical stability of anions is high, a side reaction during device driving is not generated, thereby significantly improving stability and reliability of an electrochemical device.
